Viewing time scale for display
You can select to view from 12 minutes to 24 hours of data on the screen; 24
minutes (00:24) is the default. When you change the time scale, that scale remains
in effect the next time you access the trend screen.
Press the left (-) or right (+) side of the function key to decrease or increase,
respectively, the viewing time scale. The available options are as follows:
00:12 or 00:24 minutes
01:00, 02:00, 06:00, 08:00, 12:00, 16:00, 20:00, or 24:00 hours
At the shortest time scale (12 minutes), each pixel column on the trend graph
represents one six-second data point. A single numeric value appears to the left of
the cursor.
For longer time scales, each pixel column represents multiple data points. The
lowest and highest values for the range of data points at the cursor appear to the
left and right of the cursor line, respectively. When the cursor is on multiple data
points, the time and date of the oldest data appear at the bottom of the screen.
•
If you change the time scale to be longer or shorter while viewing a column of
trend data, the time and date shown do not change.
•
If no valid data exist at a column, dashes represent “no value,” and the time
and date are shown.
•
All power-off cycles appear on the trend graph regardless of the time scale
selected.
The trend data are maintained in the monitor as long as the monitor’s battery is
connected and charged to minimum operating level.
